ReSharper 2023.3 Early Access Program Begins!

Sasha Ivanova

Hello everyone,

The Early Access Program for ReSharper 2023.3 has started! Before you download the first EAP build, let’s take a look at what is in store for you.

Working with aliases

With this first EAP build, we are introducing support for C# 12’s ability for alias directives to reference any kind of type.

We’ve also made a number of changes to improve your overall experience using aliases. Here are just a few:

• The Go to Declaration command now allows you to go to using directives (RSRP-491637).
• In the past, our code-generating features would often lose aliases when producing code and you would see the underlying aliased symbol instead. This issue has now been resolved.
• We’ve introduced better tooltips on alias usages.
• New inspections (Use type alias and Use namespace alias) and corresponding quick-fixes are available.

• The new Introduce type alias context action for selected type usages is available.

• The new Use this type alias where possible context action for using alias directives is available.
• The new Inline ‘using’ alias context action is available.

Inspections targeting Entity Framework-related issues

ReSharper 2023.3 EAP 1 brings new inspections for usages of methods in Entity Framework-related code that could potentially produce runtime exceptions. 

The 2 cases covered by these new inspections are:

1. Methods that produce exceptions when called on in a database context while not being convertible to SQL within Entity Framework or Entity Framework Core.

2. Methods that produce exceptions when called on outside of a database context while being exclusively implemented as database functions.

Performance 

Finding usages of types and constructors is now faster for solutions with numerous target-typed object creations (e.g. SomeType _field = new() ). This improvement also positively affects refactoring speed. 

We’ve also fixed some issues associated with handling injected languages, which used to cause increased CPU usage. 

C++ language support

ReSharper C++’s Early Access Program for 2023.3 starts off with a few nice additions for Unreal Engine projects, like improved generation of hash functions and a new inspection for dynamic delegate functions not marked with the UFUNCTION macro.

The first EAP build also includes a set of warnings for redundant or incorrect usages of the export keyword in C++20 modules, improved handling of void parameter lists in C code, and support for the #pragma region and #pragma endregion directives.

 For more details on the ReSharper C++ updates, see the dedicated blog post.
